Taking on the lead challenge: State and community action accelerates across the country

Sam Lovell, Project Manager and Tom Neltner, J.D., Chemicals Policy Director.

In January, we reported on the tremendous progress made by states and communities in 2018 to replace lead service lines (LSLs) – the estimated 6.1 million lead pipes across the country that connect homes and other buildings to the water main under the street. At that time, our tracker stood at 95 communities and 16 states working to replace LSLs.

Half a year later, and the total number of communities (including municipalities and water utilities) EDF has learned of that are leading the way has swelled to 181.[1]

  • 7 communities located in Massachusetts, Michigan, Oregon, South Dakota, Washington, and Wisconsin have publicly announced that they completely replaced all known LSLs.
  • 108 communities have publicly set a goal of eliminating LSLs on public and private property, totaling more than 381,000 LSLs. Nearly ¾ of these communities are served by the investor-owned utility, American Water’s, operations in Missouri (34 communities), Indiana (27 communities), and Pennsylvania (19 communities). For the remaining states, Wisconsin is leading the way with 11 communities followed by Michigan with five; Colorado and Massachusetts with two; and Arizona, Arkansas, Montana, New Jersey, and Washington each with one.
  • 66 communities are publicly taking steps to replace LSLs but have not yet set a goal of full replacement. These communities include 15 in Wisconsin; 12 in New York; 11 in Illinois; seven in Michigan and Massachusetts; five or fewer in Colorado, Iowa, Kentucky, Minnesota, New Jersey, Ohio, Pennsylvania, Rhode Island, Texas, Vermont, and Virginia; and Washington, D.C.

Lead from new “lead-free” brass faucets? An update on progress

Tom Neltner, J.D. is the Chemicals Policy Director and Lindsay McCormick is a Program Manager.

Last year, we discovered and reported in a blog, that some new brass faucets that meet existing standards and are labelled “lead-free” can still leach significant amounts of lead into water in the first few weeks of use. Here, we answer some questions that have come up and provide an update on efforts to revise the NSF/ANSI 61 standard to better protect and inform consumers.

Last November, the committee responsible for revising the NSF/ANSI 61 standard convened a group to consider an optional certification for faucets that meet a more protective limit. A study of more than 500 models of faucets showed that 73% of faucets leach less lead into water and can meet a limit that is five times more protective for children. However, currently there is no easy way to identify these “lower lead” models. The optional certification would enable consumers, schools, and child care facilities to identify and purchase faucets that leach less lead to drinking water.

Unfortunately, as described later in this blog, representatives of the brass faucet manufacturers have worked to block the optional certification. As of August 2019, the committee has not decided whether to move forward with a proposal for the optional certification to receive public notice and comment. If the committee fails to move forward, we anticipate that some major retailers that sell brass faucets and other major buyers such as school districts and builders would use their leverage to set higher standards in their purchasing specification that favors models performing better on the NSF/ANSI 61 lead leaching test.

Denver Water proposes innovative plan to remove an estimated 75,000 lead service lines in 15 years

Lindsay McCormick, is a Program Manager. Tom Neltner, J.D., is the Chemicals Policy Director.

Update (9/10/19): Denver Water is currently taking comment on its final proposal through October 10, 2019.  Denver Water will present feedback received to EPA and CDPHE. If you would like to weigh in, you can submit comments here.”

Yesterday, Denver Water’s board approved its proposed “Lead Reduction Program Plan” to fully replace the estimated 75,000 lead service lines (LSLs) in their system within 15 years.  The plan is an innovative solution that will remove the primary source of lead within Denver Water’s system, while avoiding the use of orthophosphate that can further exacerbate nutrient pollution problems in rivers, streams and oceans, an issue EDF’s Ecosystems team is working hard to solve.

As proposed, Denver Water would fund full replacement of LSLs through water rates, bonds and sales of new connections to the system, hydropower production and other sources rather than have individual property owners contribute.  In addition, the utility’s proposal to provide filters to residents until their LSLs are replaced represents a model other communities should consider based on the effectiveness of their ongoing pilot.  Before implementing the plan, Denver Water will need to receive approval from the Environmental Protection Agency (EPA).

ASDWA releases useful guidance to help states develop lead service line inventories

Tom Neltner, J.D., Chemicals Policy Director and Lindsay McCormick, Program Manager

As we have explained in past blogs, it is critical that states have rough estimates of how many lead service lines (LSLs) each drinking water utility in the state may have in order to develop sound policy decisions and set priorities. Congress recognized the importance of LSL inventories when it directed the Environmental Protection Agency (EPA) in the America’s Water Infrastructure Act of 2018 to develop a national count of LSLs on public and private property in the next round of the 2020 Drinking Water Infrastructure Needs Survey. States have a crucial supporting role in the Needs Survey since it is the basis of allocating State Revolving Loan Funds to the states.

This month, the Association of State Drinking Water Administrators (ASDWA) released a useful guidance document to help states develop LSL inventories. The guidance builds on the lessons learned from:

  • Mandatory surveys conducted by California, Illinois, Michigan, and Wisconsin;
  • Voluntary surveys conducted by Indiana, Massachusetts, North Carolina, and Washington; and
  • Responses to requests for updated Lead and Copper Rule (LCR) service line preliminary materials inventories conducted by Alabama, Louisiana, Kansas and Texas.

EPA distorts the scientific evidence and fails to protect kids’ brains in its proposed limit for perchlorate in drinking water

Tom Neltner, J.D.is Chemicals Policy Director and Maricel Maffini, Ph.D., Consultant

Today, the Environmental Protection Agency (EPA) proposed a Maximum Contaminant Level (MCL) of 56 parts per billion (ppb) for perchlorate in drinking water – more than three times less protective than an interim health advisory level set in 2008. To justify this increase, EPA turned its back on scientific evidence showing that this potent neurotoxin undermines childrens’ motor development and control and can increase their anxiety and depression. The agency’s reasoning is inconsistent with its own analysis published in a draft report in late 2017 and the findings of a peer review panel it convened last year to review that report.

If the agency had used the most protective scientific study and the most sensitive endpoint evaluated in the proposed rule, the MCL would likely be 4 ppb – more than three times more protective than the current health advisory. As a result, the agency fails to adequately protect children from a lifetime of harm. With this MCL, EPA is allowing pregnant women to be exposed to perchlorate in the first trimester of pregnancy at levels that pose much greater risk of impaired neurodevelopment in their children.

The proposed MCL – and how the agency reached it – was both a disappointment and a surprise to us. In late 2017, we applauded the agency’s scientists for developing an innovative model connecting a mother’s perchlorate exposure in the first trimester to fetal harm. We were not alone – in early 2018, EPA’s peer review panel congratulated the agency’s scientists on their analysis. We also complimented EPA’s population-based approach to developing an MCL by estimating the percent of pregnant women, and their children, with borderline thyroid dysfunction due to low iodine intake.

So how did EPA abruptly change course and estimate an MCL less protective than the current health advisory? By altering its analysis in three subtle but significant ways:

  1. Rejecting five epidemiology studies showing harm at even lower exposure levels in favor of one IQ study by Korevaar et al. in 2016.
  2. Choosing an MCL that allows an IQ loss of 2 points even though the study showed a 1 point loss was statistically significant.
  3. Dismissing an alternative, population-based method that EPA proposed in 2017 that reinforces the need for a more protective standard.

EPA’s safety standard for perchlorate in water should prioritize kids’ health

Tom Neltner, J.D.is Chemicals Policy Director and Maricel Maffini, Ph.D., Consultant

The Environmental Protection Agency (EPA) will soon propose a drinking water standard for perchlorate. The decision – due by the end of May per a consent decree with the Natural Resources Defense Council (NRDC)— will end a nearly decade-long process to regulate the chemical that has been shown to harm children’s brain development.

In making its decision, EPA must propose a Maximum Contaminant Level Goal (MCLG) “at the level at which no known or anticipated adverse effects on the health of persons occur and which allows an adequate margin of safety.”[1] It must also set a Maximum Contaminant Level (MCL) as close to the MCLG as feasible using the best available treatment technology and taking cost into consideration.

To guide that decision, EPA’s scientists developed a sophisticated model that considers the impact of perchlorate on the development of the fetal brain in the first trimester when the fetus is particularly vulnerable to the chemical’s disruption of the proper function of the maternal thyroid gland. As discussed more below, the model was embraced by an expert panel of independent scientists through a transparent, public process that included public comments and public meetings.

In April, a consulting firm published a study critiquing EPA’s model. The authors acknowledged the model as a valuable research tool but did not think it is sufficient to use in regulatory decision-making due to uncertainties. Therefore, the authors concluded that EPA should discard the peer-reviewed model and rely on a 14-year old calculation of a “safe dose” that does not consider the latest scientific evidence and has even greater uncertainties. They didn’t offer other options such as using uncertainty factors to address their concerns about the model’s estimated values.

Given the importance of the issue and the risk to children’s brain development, we want to explain EPA’s model, the process the agency used to develop it, and the study raising doubt about the model.
